Hello all! I was hoping someone might be able to point me in the direction of a fic that I know I have read so many times (and somehow can't seem to find right now ...argh)

Hey there! So, I've been looking for fics that revolve around two themes:

1) AU or Non-AU fics where Castiel, while still being an angel, has a child or children or at least is a present parental figure in a child's life.

2) AU or non-AU fics where Dean and Cas, or either, have a sick child. Established, pre-relationship or gen is totally fine.

I'd appreciate enormously if you'd point me in the right direction. Thanks in advance!
